Photoautotroph

Photoautotrophs - plants, algae, and some bacteria - use light as the source of the needed energy. [Photosynthesis]
Chemoautotrophs use the energy secured by oxidizing some inorganic substance in their surroundings.

Most plants are photoautotrophs, which means that they are able to synthesize food directly from inorganic compounds using light energy -for example the sun, instead of eating other organisms or relying on nutrients derived from them.

Members of this genus are photoautotrophs that can generate chemical energy through an electron transport chain in the cytoplasmic membrane that is associated with a light-harvesting complex housed in a specialized organelle called the chlorosome.

Plants are photoautotrophic. However, some eucaryotic microorganisms are not limited to just one nutritional mode.

These terms are often combined. So, a "photoautotroph" is an organism that, like plants, gets its energy from light and its carbon from CO2. Decomposers are often chemoheterotrophs; they may obtain energy and carbon from the same source.

Most plants are autotrophs, as are many protists and bacteria. Contrast with consumer. Autotrophs may be photoautotrophic, using light energy to manufacture food, or chemoautotrophic, using chemical energy.
